Traction control light and engine light come on and off

What is your question?

Traction control light and engine light come on and off periodically the engine feels like it's going to die, pulled codes it says misfire and change coils,pluggs,and wires so I have twice now and its stops for a little while then it happens again. I did get different coils than what was originally on it not sure if that has anything to do with it. They are square and I thing the other ones where round Not sure what my next step would be. Do you thing it would be due to the different coils?

What makes this problem better or worse?

Not sure
